Question 13 (1 point) Solve the problem. Suppose a random sample of n measurements is selected from a binomial population with probability of success p = .28. Given n = 250, describe the shape, and find the mean and the standard deviation of the sampling distribution of the sample proportion, p. skewed right; 98, 8.40 approximately normal; 0.28, 0.449 Oapproximately normal; 0.28, 0.028 approximately normal; 0.28, 0.024 Question 14 (1 point) Answer the question True or False. In most situations, the true mean and standard deviation are unknown quantities that have to be estimated. True False
